Description

  The present invention relates to a knife including a knife or the like, and relates to a knife having a blade shape in which a semicircular shape is continuously formed with respect to the blade of the knife.

  Originally, a knife blade is formed in a straight line and used to cut an object. In particular, in order to enhance sharpness, a straight blade is formed with a sharp cross section and used as a sharp tool. However, depending on the object to be cut, there is also used a knife including a knife having a so-called wave blade in which the blade is formed in a wave shape instead of a straight line and a substantially triangular wave blade is continuously formed.

  This is because, for example, a triangular wavy blade, that is, a concave portion is continuously formed when cutting a bread or the like, and a product is formed by sequentially contacting the product for cutting with this portion as a convex portion between the concave portions. Cutting. For example, wave blade knives are used for cutting soft sponge-like products such as bread to prevent crushing. Further, the convex portions of the triangular wave blades sequentially contact the product, so that the product can be cut, for example, like a saw blade, and the shape related to cutting the product with the wave blade is used. Exists.

  For example, as shown in Japanese Patent Application Laid-Open No. 2001-190864 (Patent Document 1), there is a wave blade knife, and there is also one that increases the cutting efficiency by changing each curvature of the arc-shaped recesses formed continuously. To do. Furthermore, utility model registration No. 3203377 (Patent Document 2) as a knife having a wave blade, and utility model registration No. 3186310 (Patent Document 3) as a knife having two kinds of wave blades as knife blades. Exists.

  As described above, regarding knife blades including kitchen knives, arc-shaped recesses are continuously formed according to the type of object to be cut, and wave-blade blades having protrusions are formed between the arc-shaped recesses. The knife you have is what you are using. In this configuration, the object to be cut sequentially contacts the side of the convex part of the wave blade, and hits the side part of the object to be sequentially cut from the opposite direction, further separated by the concave part, and further on the side surface of the continuous convex part. The cutting efficiency is increased by bumping from the facing direction, and the convex portion sequentially hitting from the facing direction with respect to the portion that is cut away by the concave portion and so forth.

  This means that the convex part of the corrugated edge part of the blade edge part which is a blade part having a cross-sectional protruding shape that comes into contact with the one to be cut sequentially hits, and the blade edge that is the blade part is likely to wear, and the sharpness is It tends to decline. Therefore, it is desired to use the shape of the blade edge that is a blade portion that is easier to cut and has less wear. Thus, a knife having a blade using another shape instead of a wave blade is desired.

  Furthermore, for blades for soft products, sponge-like products, etc., wave blades are used rather than those having a normal linear cutting edge. Therefore, it is desired to provide a knife that can easily cut at least a softer product than this wave blade, a sponge-like product, etc., and has a sharpness. As described above, it is desired to provide a knife that can cut sharply when cutting a knife including not only soft products and sponge-like products but also ordinary products, and has high cutting efficiency and is easy to use.

  In order to solve the above-mentioned problem, the invention according to claim 1 is composed of a convex arc blade knife having a cutting edge in which a large number of small convex arcs are successively formed, and the problem can be solved by such an idea. . Or you may use the convex arc blade knife which has the blade edge | tip formed by the concave circular arc between the convex arcs which adjoin continuously like the device which concerns on Claim 2.

  In addition, a convex arc blade knife having a cutting edge in which convex arcs and concave arcs are alternately and continuously formed as in the invention according to claim 3 may be used. In these cases, as in the invention according to claim 4, the convex arc and the concave arc are arcs having different radii of the respective circles, and form an arc of the convex arc and the concave arc. A convex arc with a radius of the circle to be convex is a convex arc blade knife having a cutting edge which is a convex arc made of a circular arc of a circle having a longer radius than that of the concave arc. The above problem can also be solved by a convex arc blade knife.

  Further, the invention according to claim 5 has a cutting edge composed of convex arcs that are sequentially formed at intervals of at least five convex arcs that are continuously formed in one inch (2.54 cm). It consists of a convex arc blade knife, and this configuration can also solve the problem.

  Instead, the cutting edge is formed of convex arcs that are successively formed at intervals of four convex arcs formed in one inch (2.54 centimeters) as in the device according to claim 6. A convex arc-blade knife having the following may be used. In the configuration described above, a convex arc blade knife in which the convex arc blade knife is a knife may be used as in the device according to claim 7.

  By using the convex arc blade knife according to the present invention, the arc-shaped tip portion of the blade edge sequentially traces the surface of the object to be cut, and the cutting can be performed in a state where the blade edge slides, so that the cutting can be performed more reliably and easily. It will be a thing. Furthermore, the cutting edge can be easily maintained in contact with the product at the time of cutting, and it is possible to provide a knife that is easy to cut and sharp.

  In particular, according to the first aspect of the invention, since the small convex arc is continuously formed, the cutting edge can be easily cut by drawing or pushing the surface of the object to be cut more smoothly. Further, according to the invention according to claim 2, since the convex arcs adjacent to each other are formed as concave arcs, the cutting edge is in contact with what should be cut more smoothly between the convex arcs. It can slide easily into what is to be cut.

  Further, since the convex arcs and the concave arcs are alternately and continuously formed according to the invention according to claim 3, when the blade tip is in contact with the one to be cut as described above, the blade tip is in contact with the one to be cut. It can be slid and cutting efficiency can be maintained high. According to the invention according to claim 4, the convex arc can be made into a long arc, the concave arc can be made into a short radius, and the cutting edge can cut into a large convex arc that cuts into what should be cut when cutting. High efficiency can be maintained.

  Further, the invention according to claim 5 is an optimal example of the installation state of the continuously formed convex arc cutting edge, and can provide a convex arc cutting knife having a cutting edge that can be cut efficiently.

  Furthermore, similarly, the invention according to claim 6 is an optimum example of the installation state of the continuously formed convex arc cutting edge, and can provide a convex arc cutting knife having a cutting edge capable of cutting efficiently. . The invention according to claim 7 makes it possible to provide a convex arc blade knife that can be applied to a knife in particular among knives.

The figure which shows an example of the convex arc blade knife which concerns on this invention The figure which shows an example of the back surface of the convex arc blade knife which concerns on this invention shown in FIG. The enlarged view which shows an example of the blade edge | tip of the convex arc blade knife which concerns on this invention shown in FIG. The figure which shows another example of the convex arc blade knife which concerns on this invention The figure which shows an example of the back surface of the convex arc blade knife which concerns on this invention shown in FIG.

  FIG. 1 is a view showing an example of a semicircular continuous blade knife according to the present invention. The knife shown in this figure has a configuration related to a knife in particular, and is composed of a handle 2 and a blade 1 portion, and the blade 1 portion has a peak portion 10 and a blade portion, that is, a blade edge 11 in the opposite direction. The tip of the blade 1 is pointed and forms a cutting edge 12.

  The blade portion, that is, the blade edge 11 has a blade edge shape in which both end portions are formed in a straight line shape, but a convex arc 110 is formed continuously except for the both end portions. That is, small convex arcs 110 are successively formed, and concave arcs 111 are formed between adjacent convex arcs 110. Accordingly, the knife has a cutting edge 11 in which convex arcs 110 and concave arcs 111 are alternately and continuously formed.

  As a result, the cutting edge 11 is all formed in an arc shape. From this, when cutting the object to be cut using the blade edge 11, the arcuate tip portion sequentially traces the surface of the object to be cut, and the cutting edge 11 can be cut while being slid. That is, it is possible to maintain a high state that the cutting edge 11 is always in contact with the product at the time of cutting, and it is possible to perform cutting more reliably and easily in a state where the cutting edge can be maintained at a position to be cut of the product. It becomes.

  This means that a wave blade knife that moves by cutting a blade tip having a wavy triangular convex portion in a direction transverse to the protruding direction of the convex portion should be cut. Cutting is performed by sequentially coming into contact with the product from a distant position, and the cutting edge is intermittently touched. The cutting edge and the cutting edge are bumped by the convex part of the wave blade and repeatedly cut away by the concave part. To be.

  In contrast, according to the present invention, between the blade edge 11 and the object to be cut, the cutting edge 11 comes into contact with the cutting edge 11 in a state where the blade edge 11 slides. The cutting efficiency can be maintained at a high level. Therefore, for example, even when soft and sponge-like products such as bread are cut, it is possible to provide a knife that is extremely difficult to produce bread crumbs. In particular, it is possible to provide a knife that can be cut smoothly without being caught because the blade edge 11 continuously touches a soft object. Furthermore, since unnecessary force is not applied, cutting can be performed more easily and wear of the cutting edge can be reduced.

  FIG. 2 is a view showing the back side of the surface of the knife shown in FIG. It is a figure which shows an example of the kitchen knife which has the single-edged blade which has a cutting blade in the blade-tip 11 part of the convex circular arc 110 and the concave circular arc 111 which are formed sequentially as shown in this figure. Particularly with respect to kitchen knives, the strength of the cutting edge 11 can be maintained while maintaining the sharpness by the single-edged configuration, and the wear can be reduced. Of course, the knife of FIG. 1 may be of a knife having a double-edged blade.

  FIG. 3 is an enlarged view showing the cutting edge 11 of an example of a semicircular continuous blade knife according to the present invention in an enlarged manner. As shown in this figure, convex arcs 110 are formed successively in succession, and the cutting edge 11 is formed with a concave arc 111 between adjacent convex arcs 110. In this configuration, the convex arc 110 and the concave arc 111 are arcs having different radius lengths, and the radius of the circle forming the arc of the convex arc 110 and the concave arc 111 is long. The convex arc 110 is formed by a circular arc having a longer radius than the concave arc 111.

  The ratio of the lengths of the radii of the circles is not limited to that shown in the figure, and may be formed by other ratios. Alternatively, the circular arcs that form the convex arc 110 and the concave arc 111 may have the same radius. However, the convex arc 110 is formed to be larger by using an arc made of a circle having a longer radius than the concave arc 111, and the contact portion with the one to be cut is made larger. Therefore, it is desirable that the convex arc 110 has the convex arc 110 and the concave arc 111 formed by a circle having a longer radius than the concave arc 111.

  Next, it is optimal that the convex arcs 110 are provided on the cutting edge 11 shown in this drawing at intervals of at least five convex arcs 110 within one inch (2.54 cm). This is because the convex arcs 110 of the cutting edge 11 are successively formed with respect to the cutting edge 11 in which the convex arcs 110 are continuously formed. When a convex arc blade knife having a cutting edge 11 in which an arc 110 is continuously formed cuts a portion in which the cutting edge 11 portion of the convex arc 110 is easily crushed, such as a pan, the blade edge 11 is slid onto the bread to be cut. 1 shows an example of the configuration of the blade edge 11 having an interval that can be cut in an optimum manner without crushing a pan or the like that can be touched in a state where the bread is crushed.

  In this case, when the cutting edge 11 forming the concave arc 111 is formed between the convex arcs 110 that are continuously formed, the convex arc 110 and the concave arc 111 are successively formed in order. After passing through at least five convex arcs 110 from one concave arc of the cutting edge 11 continuously forming the convex arc 110 and the concave arc 111 that continues further from the most concave bottom portion of the concave arc 111 of one concave arc 111 The convex arc 110 and the concave arc 111 are continuously formed at an interval of 1 inch (2.54 cm) to the most concave bottom portion of the concave arc 111 of the concave arc. This is an optimal example.

  That is, in the cutting edge 11 in which the convex arc 110 and the concave arc 111 are continuously formed, the concave arc 111 of the cutting edge 11 continues from the convex arc 110 to the subsequent concave arc 111, and the convex arc following this. 110 and a cutting edge 11 sequentially formed, and at least 5 from one concave arc 111 of the cutting edge 11 in which a convex arc 110 and a subsequent concave arc 111 are continuously formed from the most concave bottom portion of the concave portion of one concave arc 111. The convex arc 110 and the concave arc 111 are spaced at intervals of 1 inch (2.54 centimeters) to the most concave bottom portion of the concave arc 111 after passing through the two convex arcs 110. A configuration having cutting edges that are continuously formed is an optimal example.

  The cutting edge 11 in which the convex arc 110 and the concave arc 111 are continuously formed at this interval is one of the configurations that can be easily cut as the cutting edge 11 that cuts a crushed pan or the like as described above. The length from the concave portion of the concave arc 111 to the most concave bottom portion of the concave arc 111 after passing, for example, about four convex arcs 110 is not limited to these, but is 1 inch (2.54 cm). It is also possible to configure the interval at a certain distance (meter), and naturally the intervals slightly before and after the intervals shown are naturally the same intervals included in these.

  Of course, the convex arcs 110 that are simply formed continuously may be configured to have an interval of about four in one inch (2.54 cm). FIGS. 1 to 3 show the configuration of the convex arcs 110 formed successively in succession, but these consecutive arcs 110 are all continuously arcs having the same radius. It shows what is formed.

  Since this shape forms the cutting edge 11 at the same interval, the cutting condition at the time of cutting can be set to the same level as a whole, but not limited to this, the consecutive convex arcs 110 have the same radius length. It may have a cutting edge 11 formed by continuously forming a convex arc 110 using arcs having different diameters using arcs having different radius lengths instead of coincident with the arc having.

  FIG. 4 is a diagram showing an example of a knife having a convex arc 110 and a concave arc 111 that are successively formed on the blade edge 11 of a knife having a blade 1 portion having another shape. The configuration shown in the figure shows an example of a knife having an optimum blade 1 as a bread knife or cake knife. As shown in the figure, the vicinity of the cutting edge 12 portion and the vicinity of the jaw 13 have a straight cutting edge 11, but all of the other than the both end portions have a cutting edge 11 formed by sequentially forming a convex arc 110. A knife.

  Since at least the portion of the cutting edge 11 can be cut in contact with what should be cut sequentially by the convex arc portion by a knife having the cutting edge 11 formed by sequentially forming the convex arc 110, it is necessary to have such a configuration. It is. Further, in the configuration of this figure, as in FIGS. 1 to 3, the convex arcs 110 that are successively formed are formed with concave arcs 111 between the convex arcs 110 that are successively adjacent to each other.

  Therefore, it may be formed with a knife having the cutting edge 11 in which the convex arc 110 and the concave arc 111 are continuously formed. With such a configuration, the cutting edge 11 that is to be cut more smoothly can be obtained. The contact portion can be slid in a sliding state, and cutting can be achieved, thereby enabling smoother cutting.

  FIG. 5 is a view showing the back surface of the knife shown in FIG. 4, and in this drawing also shows a knife 1 having a cutting edge 11 having a cutting edge 11 having a single-edged cutting edge 11. Accordingly, it is possible to provide a knife that is extremely easy to cut.
